I am having a problem retrieving codec output and listing the bytes.
Following the Breno/Sparks thread I was able to get past the errors
with initializing Audio Record and my code seems to run but I get all
0's as output. I assume I am missing something in AudioRecord.read? I
am trying to look at the contents of the byte array (saveBytes) after
recording has stopped.
my code looks like this
*************************************************************************************************
// tune class (main display)
RecordTone.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
try
{
// init code recorder
ar_test = new AudioRecord
(MediaRecorder.AudioSource.MIC, 8000,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT, 150000);
int status = ar_test.getState();
}
catch (IllegalArgumentException e)
{
e.printStackTrace();
}
ar_test.startRecording();
while(bytesRead < 40000){
bytesRead = ar_test.read(saveBytes, 0, 40000);
}
ar_test.stop();
}
}
*************************************************************************************************
//display list of codec output
arTest = new tune();
String[] arResults = new String[arTest.saveBytes.length];
System.out.println("lgth+"+arTest.saveBytes.length);
arResults[0] = "List";
for(int ii=1; ii<arTest.saveBytes.length-1; ii++){
arResults[ii] = Byte.toString(arTest.saveBytes
[ii]);
}
setListAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, arResults));
final ListView listView = getListView();
